ELECTRIC WELDING APPARATUS.

, To all whom it may concern:

Be it known that I, JOHN P. NIKONOW, a citizen of Russia, and a resident of the city of Dayton, in the county of Montgomery and. State of Ohio, have invented a new and useful Improvement in the Electric Welding Apparatus, of which the following is a specification.

' My invention relates to the electric welding apparatus and it has particular reference to such mechanism as embody manually controlled electric arc.

. The object of my invention is to provide a simple and convenient arrangement, whereby an electric arc'can be maintained between the electrodes of a portable apparatus, which can be manipulated with one hand, the length of the are being controlled by the movement of the fingers of the same hand. I i I In the construction of electric welding apparatus, diificulties have been encountered because of lack of a' convenient arrangement to control the distance of the are from the work and at the same time the length of the arc, itself.

Accordin tovmy invention, I employ an electric wel ing apparatus, comprislng two ccarbon electrodes, movably attached to the parts of a portable and manually operated frame, so that the apparatus can be held in one" hand at a proper distance from the piece to be welded and at the same time, the distance. between the electrodes can be continuously controlled by the movement of the fingers.

In the accompanying drawings, Figure 1', is a side view of the apparatus and Fig. 2 end view (section), showing attachment of the eye protecting lass.

Electrode 1 is p aced in a metal clamp 3, attached to a metal bar 4 with an insulated handle 5; Insulated. blocks 6 and 7 are fastened to the bar 4 and form guides for the Y movable bar.8, which supports electrode2 with the clamp 9. S ring 10 tends to move the bar 8 and electro e 2 away from the electrode 1, but the electrodes may be brought in contact or kept at a desired distance by means of a fingerhook 11, insulated from the Specification of Letters Patent.

bar 4 means of a bushing 12. Electric conductors 13 pass through the hollow handle 5, one lead being attached to the bar 4, the other to the bar 8 by means of the screw 14. Dark glass 15 in a frame 16 is attached to the bar 4 and serves to protect the eyes and face of the operator from direct radiation of the are between electrodes 1 and 2.

A suitable transformer'(not shown) may be employed between the conductor 13 and the source of the current, in order to obtain suitable low voltage at the proper current.

An important advantage of the mechanism above described'is, that it can be easily manipulated and controlled with one hand,

so that welding, brazing, soldering or heating can be done on the pieces without discurbing. their position or removing them rom their position.

I claim as my invention:

1. In an electric welding apparatus, the combination with the electrodes, slidably mounted in relationto each'other, one electrode having a handle and the other a finger trigger, and means for conducting electric current to said electrodes.

2. In an electric welding apparatus the v combination with the electrodes, slidably mounted in relation to each other,'one electrode having a handle and. the other a fi'nger trigger, a means for conducting electric current and a protecting reflector, fastened to one of the electrodes.

3. In an electric welding apparatus, the

combination with the electrodes, slidably mounted'in relation to each other, and a manually o erated controlling device forsaid electro es, consisting of a sliding frame ,with a finger trigger. .4. In an electric welding apparatus, the

combination with the electrodes, slidably mounted in relation to each other, a manually operated controllin device for said electrodes, consisting of a s iding frame, sup- .porting one of said electrodes, with a finger tr1gger 1n a working relation to the'handle, attached to the other electrode.
